Description

Phenylpropiolaldehyde CAS NO 2579-22-8 is a versatile aromatic alkyne derivative, characterized by its terminal aldehyde and triple bond functional groups. This unique structure makes it a highly valuable building block in advanced organic synthesis, particularly for the construction of complex heterocycles and pharmaceutical intermediates. It is essential for research and development chemists in the pharmaceutical, agrochemical, and fine chemical industries seeking to introduce conjugated systems and reactive handles into target molecules.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those containing indole, quinoline, or other fused heterocyclic cores.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators that require specific aromatic-aldehyde functionalities.
• Fine Chemical Production: Serves as a critical starting material for dyes, pigments, and optical brighteners due to its ability to form extended conjugated systems.
• Material Science Research: Employed in the creation of organic semiconductors, liquid crystals, and metal-organic frameworks (MOFs) where precise molecular architecture is crucial.
• Academic & R&D Laboratories: A valuable reagent for methodology development in click chemistry, cycloaddition reactions, and cross-coupling protocols.

Quality Control

Our Phenylpropiolaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its properties of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, open flames, and strong oxidizing agents.
